.i new and useful Improvements To all whom it may concern:

States, residing at Baltimore, State of Maryland, have invented in Telephone- Supports, of which the follow' g is a speciication.

- This invention relates to telephonesupports, *the object Aof theinvention being to provide a simple device Oi this character which can be inexpensively and easily made.

rangedto resist action of to each other during their swing,said .s ringl position, which may be approximate The support. involves in its make-up a pair of links -mounted in some suitable manner, and associated with the links is a bracket for carrying a telephone or any other suitable device an a spring of any suitable character, arthe links relatively at the same time servin to counterba ance an article; such as a telepone, on the bracket in the different positions assumed by said bracket. It will therefore be apparent that by the construction outlined there is no tendency on the partof the links toIInove in either direction of their own action.. It repower to swing the links either to a y verti cal, or to any position between said primary or-vertical position and ahorizontal position.

' In the present instance the links mentioned are cooperative with a turnable member, by -virtue of which the bracket can be revolved support,l

to render the same readily accessible, andI provide means to prevent undue motion of said turnable member and consequentkinking of telephone-wires, and I do this in such a Way that there is no possibility of any ofthe parts being broken or in'ure have termed ythe evice a telephoneand have done so simply for convenience and also for the fact that the artited for carrying one or he support may, howelver, be usedin conjunction with other artic es.

In` the drawings accompanying aidfrma part of this specification I illustrate an a a ptation involving my invention, which willfully set forth in the followin description; butfI do not limit myself tolie disclosure thus made, for material variations may be adopted Within the scope of my claims lucthe device, showing -two of saidl turnable members or Patented July 24, 190e.

ceedingnsaid description. I desire t'o state at this time that in the specification I employ certain terms descriptive of certain parts, and I desire it to be understood that these terms are used in their broad senses.

Referring to the drawings, Figure 1 is a iront elevation of a support involvingm nvention and showingfthe same arran ed for stitut'l the other up. Fig: 2 is a detail view oan outer link. Fig. 31s a similar view of a slide or sleeve which is illustrated in Fig. l as operative with each inner link. Fig. 4 is a plan view of a bracket. through one of the arms of said bracket. Fig. 6 isv a vertical section of the lower portion of a means for limiting the motion of a turnable member or members. Fig. 7 is a plan view in Fig. 6. Fig. 8 is a detail view o a spring. Fig. 9' is a detail view in perspective of a modified form of slide.

Like characters refer to like parts throughout the diiierent views.

Fig. 5 is'a sectional view Vcarrying two telephones, one pair of lin s cong part of the support being-down and of the parts re resented 'l That adaptation of the invention which I i for convenience have selected for illustration in the accom 'anying drawingsin order to indicate the advantages of said'A invention involves in its construction an attaching member, which may be oi any suitable character and which is represented as consisting of a clamp, as 2, adapted to be connected to a table,l esk, or any other like part and to be held in solid relation with such part by means of a screw, as 3, tapped through theunder jaw of the clamp and ada ted to engage the under side of the part with which theclamp 1s connected. From the shank or body of the clamp the vertically-dis osed spindle 4 is shown as rising, said s in le being illustrated as hollow or tubular or a purpose'that will hereinafter ap ear, and the same statement applies to the ub of the vsaid shank.

Upon the spindle 4 are arranged for turnv mg movement the sleeves 5, carried by the pedestals or turnable members 6, there 4i-,1g edestale represented, and their sleeves are il ustrateci as arranged in alternation upon the spindle. By reason of the construction 'ust set forth the pedestals or turnable mem ers 6 can be independently rev clved or' operated. The

lower sleeve rests upon the hub of the shank ing readily formed by casting.

To the pedestal 6 are represented as pivoted inner and outer links 7 and 8, respectively, the pivots for said links being out of line vertically. Said pivotsare represented as being on a diagonal line or a line substantially fortv-iive degrees to the horizontal, although this exact relation is not necessary.

By such relation or an equivalent one the two links 7 and 8 can be swung to a vertical or substantially vertical position, so that when all four links assume such vertical osition the device as a whole will occupy a re atively small amount of space laterally.

The upper ends of the links 7 and 8 are connected with a bracket, as 9, of spider or three-arm Jform. The link 8 is connected with the bracket 9 centrally, thereof, while the link 7 is connected to said bracket eccentrically thereof. By reason of the linkage connection between the bracket and the pedestal the bracket will'be maintained in horizontalism as the links are swung from. a vertical to a horizontalposition, and viceversa, in order to assure that a telephone or other device supported upon thebracket will' be in pro er position for use throughout the entire bac ward and forward swingof the links.

As previously indicated, the bracket 9 is illustrated as comprising three arms, two of them bein provided at their outer ends with hook-like ugs 10, while the third one is profiled at its outer endwith asleeve 11, arranged for radial movement with respect to said bracket and adapted to be maintained in an adjusted position by the head of a screw 12 tapped in to the body of said third arm. The sleeve 1 1 is provided on its upper side with a lug 10 complemental to the other two lu s 10, the three lugs serving to engage over a te e honebase or over an insulating board or isk 13, upn which'said base is a apted tol-rest and w 'ch can be connected rigidly with the bracket by-means of the three lugs. Where I use a su port with two brackets, I prefer to insulate t e two tele hones from each other by boards, as 13, irectly carried by the brackets 9, and to which the respective telephones are attached in any desirable way. The boards insulate the telephones from each other, so that sounds cannot be transmitted from one to the other Whenthey are on different circuits.

' Associated with the links in any desirable suffice for the other, similar phone, so that 'tion is release manner is a spring of any suitable character arranged to resist the action of the links relatively to each other during theirswing, and this spring is adapted to counterbalance a telephone or other article sustained upon the bracket 9 durin the swing of the links, so

,that the latter wi lhave in themselves no tendency to either move down or up. By reason of the spring, however, very little power is acquired to manipulate the I links to get them either to a vertical or horizontal or any intermediate position. The means illustrated for accomplishing the result set forth will now be described.

Surrounding the upper portion of the inner link 7 is a coiled protractile or push s ring 14, bearing at its upper end against a s ou der, as 15, on said inner link and at its lower end against a slide 16, also on said inner link, and which may consist of a sleeve. The shoulder or stop 15 is adjustable, it being represented as a nut threaded onto the link 7 and by the movement of which the tension of the spring 14 can be regulated. It will be understood that on the downwardior upward swing of the links the inner one has a relative lateral motion with respect to its companion, and it is this motion that is resisted by the spring and in such a way that the weight. of the telephone and its accessories naturally is counterbalanced no matter what the positions of the links may be within their swing.

Upon the outer link is an inwardly-extending arm 17, having a bead 18 along its ufpper edge to slidingly fit a groove 19 in the bo y of the slide or sleeve 16. It will be understood from this that the slide 16 has not onl a sliding. movement on the inner link 7, also a sliding movement on the arm or projection 17 the motions indicated occurring when the links are swung. It will be evident, therefore, that by reason of the construction described .the s ring acts against both links, the `u per en thereof acting against y.the shoul er or n ut 15, while the lower end thereof acts against the sliding sleeve 16 and, through the latter, against the arm v17 of the outer link. Practically the spring is interposed between the two links in order topppose their relative motions. l1 s When the are initially swung down, the slide 16 first ut has moves outward and subsequently moves in- .ward through the changing relations of the parts, and uring such downward swing the `s ring is compressed by the movement ofthe s ide 16 toward the bracket 9 to increase in efficiency or power and in a ratio proportionate to the increase in momentum of the teleno matter what the positions of the bracket may be the telephone thereon will be counterbalanced by the spring. One hand, therefore, is only necessar to swing the instrument down, and when t e which was grasped to erform the o (il the links w1 lremain in the ration lnques- 35 tion.

\ 4-scription that both sets of links can be swung 'v f ,--about the links, and I vdo this Y that no possible injury canresult when the adjusted position.A As

previously indicated,

but a very small amount of power will be re- -quired to swing the links upward. To prevent the overthrow of the links, I provide a st op, as 20, on the pedestal or turnable membei`- 6, which stop is adapted to be engaged by the outer link 8 when both links have reached their vertical positions.

It is believed that it will be understood vfrom what has been hereinbefore stated that my article-support 1 involves two members i mounted for sw1ng1ng motlon and means of a suitable character, such as a spring,

pose the relative movement of said members and to apply thereto an increasing effect o r resistance as said members swing from one position to another. This increasing effect or resistance occurs in the form ofembodiment of the invention shown, as the swinging members move from a substantially vertical to a substantially horizontal position. The spring therefore is arranged to yieldingly, increasingly, and longitudinally resist the oposing movement of the two members in reation to each other during their downward swing and to apply automatically a continui 'ous and. increasing longitudinal eect to said members as they swing stantially ,the use of a telephone ortelephones.

downward, tending to restore. them to their rimary` position. This action takes place uring the entire Adownward swingfrom the vertical or subvertical to the substantially horizontal. In some cases it maybe desired to positively hold the bracket This may be readily accomplished by means of a screw, as 21, tap ed through the 1sleive 16 andadapted tolite against the Vin 7.

It will be apparent from the foregoing de- .vertically through a range of ninety degrees andin addition to this that they are revolublymounted, so that I provide-for all ossible contingencies which might arise uring f In using the su port in connection with a telephone or telep ones I limit the revoluble of the e same 1n such a way lmotion in'order to prevent kinkingl wires or the twisting or ceiling of t limit of turning motion is reached, as I will now describe.

6o" tive with alug 23 on which'extends across Y or. hollow spindl Y sented as having a lug 22, which maybe cast desired, and coperaintegral therewith, i

a saddle or button--24,

e 4. The'saddle orl button 1A -is `transverse1y channeled or apertnred to reelivehebtoqch of a biurcated torsional to opvthe lug 22 will be bufed or 9 in-an adjusted posithe top of the tubularV s ring 25, the legs or branches of which are dlisposed within the hollow spindle and hub ofthe clamp 2. The lower ends of the spring have lateral offsets, as 26, fitting in'notches or slots in said hub, whereby the s ring is held against turning motion. It wil be apparent that as the saddle overlies the upper sleeve 5 and t at as the spring, its' mounting, s held against upward movement the s ring and saddle serve as a simple means for olding the pedestals or turnable members 6 in working or assembled relation with the spindle 4. When the pedestals or turnable'members have nearly reachedthe limit of their revoluble motion, thelug 22 will strike the lug,23 and the shock thereof will be taken up by the spring 25. In other words,

will meet a yieldable limiting device. When thetwo lugs engage, the pedestal with which the lug 22 is associated can be turned a slight distance further or until thespring 25 is tensioned to its maximum extent, and this fact will be at once indicatedto the user.

Instead of employing a sleeve 16 such as thatindicated in detail in Fig. 8, for examle, I may employ a sleeve as 27. (See ig. 8.) The sleeve 27 fis of a split lor clamp form and is' adapted to frictionally engage the inner link 7,with which it c'oacts, b tightening up the screw 28, connected witii the jaws ofthe split sleeve orA clamp.

- As previously indicated, I do not limit the use of the device to any particular field. I have described it explicitly in connectionwitha telephone, forthe reason that yit has .proven particularly satisfactory in such relation. I do not limit myself tothe use of two brackets, for'one or more than two may be employed. 4I have illustrated twoto indicate that thecoperating partsy thereof can be operated independently ofeach other.

`From what has been hereinbefore stated and upon an inspection of the drawings it will be evident that my support includes at leasttwo swinging members mounted to swing from an upper to a lower position, a bracket associated with said members, and a spring to bodily swing with said two members, -the latter coacting to compress the spring as they swing from their upper to their lower position. In the present instancethe two members alluded to consist of links, the spring being of such a character as to resist the relative endwise notion of said links to cause the gradual compression of the spring as the links move 7from a substantially vertical to asubstantially.l horizontal position, by virtue of e bracket, and hence the links, when the spring is of theproper character, have nd tendency in themselves to move in either an upward or' a downward direction, the result being that the parts stay in adjusted posiby reason ofroo IIO

tions Without the necessity of employing positive -holding devices for the purpose.
